Definitions

  • the invention relates to a head-up display and its use in a vehicle.
  • Head-up displays for vehicles are generally known in the state of the art. They comprise a display unit with a screen to display information, an imaging unit and possibly an optical module to project pictures onto the screen.
  • the screen is transparent and arranged in the field of vision of a driver of the vehicle.
  • KR 1020080045849 A discloses a head-up display device for a vehicle comprising a head-up display optical system, a housing unit, and a sliding cover member.
  • the head-up display optical system generates a virtual image in front of a driver and is installed in the housing unit.
  • the sliding cover member includes a sliding cover, a cover gear portion, and a driving unit. The sliding cover is moved along a guide rail formed on the housing unit and opens/closes the housing unit.
  • the driving unit provides operational power to the cover gear portion.
  • the object is achieved by a head-up display according to claim 1 and its use in a vehicle according to claim 10 .
  • a head-up display comprising a screen, a cover for the screen and a gear mechanism for simultaneously pivoting the screen and the cover around a pivot axis between a first end position and a second end position and concurrently shifting the cover relatively to the screen in such a way that the cover uncovers the screen in the first end position and completely covers the screen in the second end position.
  • the invention makes it possible to expose the screen when it is needed to display information by pivoting the screen into a first position in which it is not covered by the cover.
  • the head-up display When the head-up display is not needed, it can be pivoted into a second position and covered by means of the cover. This has the advantage that the screen can be exposed only when the head-up display is to be used, and that it can be hidden and protected by means of the cover when it is not needed.
  • the screen and the cover are pivoted between the first end position and the second end position by approximately 90 degrees.
  • the screen and the cover are arranged substantially parallel to one another.
  • This provides a compact and space-saving arrangement of the cover relatively to the screen particularly in the second end position.
  • the gear mechanism is a planetary gearing comprising a sun gear coupled directly or indirectly to the screen and to the cover, a planet gear meshing with the sun gear, and a ring gear segment meshing with the plant gear.
  • a planetary gearing of this type provides advantageously an effective and compact gear mechanism for pivoting the screen and the cover.
  • the axis of the sun gear preferably defines the pivot axis.
  • This definition provides advantageously the simplest realization of the pivot axis, without further ado to define it.
  • a screen-sided surface of the cover comprises a coupling structure co-operating with the sun gear in such a way that a rotation of the sun gear causes a shift of the cover relatively to the screen.
  • Such a coupling structure provides a simple and effective way to cause pivoting of the screen and of the cover and shifting of the cover relatively to screen simultaneously my means of rotations of the sun gear.
  • this coupling structure is a corrugation meshing with the sun gear.
  • Such a corrugation provides a particularly simple and effective coupling of the cover to the sun gear in order to shift the cover relatively to the screen.
  • gear mechanism is motor driven.
  • the gear mechanism preferably is driven by a stepper motor.
  • stepper motor to drive the gear mechanism has the advantage that a stepper motor can be controlled precisely without any feedback mechanism concerning the motors position.
  • a head-up display according to any one of the above mentioned embodiments is used in a vehicle having a vehicle dashboard equipped with a cavity for the head-up display.
  • the head-up display is arranged in the cavity in such a way that in the first end position the screen is exposed in a field of vision of a driver of the vehicle and the cover is retracted into the cavity, and that in the second end position the screen is completely contained in the cavity and the cavity is shut at least partly by the cover.
  • the head-up display is decently embedded in the vehicle dashboard.
  • the cover of the screen is integrated into a surface of the vehicle dashboard when the head-up display is not needed.
  • the cavity and the pivotable screen provide a space-saving arrangement of the head-up display in the vehicle dashboard.
  • FIG. 1 shows a head-up display according to the invention with a screen and a cover in a first end position
  • FIG. 2 shows the head-up display shown in FIG. 1 in a first intermediate position of the screen and the cover
  • FIG. 3 shows the head-up display shown in FIGS. 1 and 2 in a second intermediate position of the screen and the cover
  • FIG. 4 shows the head-up display shown in FIGS. 1 to 3 in a second end position of the screen and the cover.
  • FIGS. 1 to 4 show sectional views of a head-up display 1 according to the invention comprising a screen 2 and a cover 3 for the screen 2 in various positions of the screen 2 and the cover 3 , respectively.
  • the screen 2 and the cover 3 are arranged substantially parallel to one another and are simultaneously pivotable around a pivot axis 4 by almost 90 degrees between two end positions.
  • FIG. 1 shows the first end position of the screen 2 and the cover 3 .
  • FIG. 4 shows the second end position of the screen 2 and the cover 3 .
  • FIGS. 2 and 3 show two intermediate positions taken by the screen 2 and the cover 3 while being pivoted from the first end position into the second end position.
  • FIGS. 2 to 4 also show the position 8 of the screen 2 in the first end position in order to illustrate the movement of the screen 2 more clearly.
  • the screen 2 In the first end position the screen 2 is upright and the cover 3 sits in parallel offset below the screen 2 without covering the screen 2 .
  • the screen 2 and the cover 3 In the second end position the screen 2 and the cover 3 are arranged horizontally and the cover 3 completely covers the screen 2 .
  • the cover 3 While the screen 2 and the cover 3 are pivoted simultaneously from the first end position into the second end position, the cover 3 is shifted relatively to the screen 2 in such a way that it covers more and more the screen 2 until the screen 2 is covered completely by the cover 3 when the second end position is reached.
  • the head-up display 1 is equipped with a planetary gearing comprising a sun gear 5 coupled to the screen 2 and the cover 3 , a planet gear 6 meshing with the sun gear 5 , and a ring gear segment 7 with inward-facing teeth meshing with the plant gear 6 and guiding the axis of the planet gear 6 along a segment of a circular curve.
  • the axis of the sun gear 5 defines the pivot axis 4 .
  • the rotation of the sun gear 5 causes a pivoting of the screen 2 and of the cover 3 around the pivot axis 4 .
  • the screen-sided surface of the cover 3 comprises a corrugation (not shown in detail in the figures) meshing with the sun gear 5 and co-operating with it in such a way that a rotation of the sun gear 5 causes the shifts of the cover 3 relatively to the screen 2 .
  • the head-up display 1 further comprises a stepper motor (not shown in the figures) driving the planetary gearing via a drive shaft (not shown in the figures).
  • the planetary gearing transfers the motor force to the screen 2 and the cover 3 to cause the simultaneous pivoting of the screen 2 and the cover 3 and the concurrent shifts of the cover 3 relatively to the screen 2 .
  • the head-up display 1 is arranged in a cavity 9 of a vehicle dashboard of a vehicle.
  • the screen 2 In the first end position the screen 2 is exposed in a field of vision of a driver of the vehicle and the cover 3 is retracted in the cavity 9 .
  • the screen 2 In the second end position the screen 2 is completely contained in the cavity 9 and the cavity 9 is shut by the cover 3 .
